Definitions

• Patented, 0a. 22, 1940 UNITED STATES PATENT OFFICE Oberhausen-Holten,
• Our invention relates to the preparation of catalysts containing cobalt and magnesium oxide and more particularly of such catalysts which contain cobalt and magnesium oxide in a predetermined ratio. These catalysts may also, contain additions of activators such as thorium oxide.
• catalysts which contain, in addition to cobalt, also magnesium and, if desired, also thorium or other activators, have proven to be particularly efiicient. These catalysts contain, as a rule, about 3 to parts magnesium oxide per 100 parts cobalt. They are distinguished by a long life and can be re-used many times without their catalytic efilciency dropping and without raising of the temperature or a regeneration of the catalysts being required.
• the precipitated cobalt is in contact with the precipitating liquor for a longer period of time, the precipitate ages so that the surface structure 01 this main part of the catalyst to be prepared is unfavorably influenced. If the time of precipitation is however shortened in order to avoid this drawback, the precipitated catalyst does not contain that quantity of magnesium which is required for imparting to the cobalt its full efficacy.
• the efilcacy of the catalyst to be prepared can precisely be controlled by adjusting the excess of magnesium employed.
• the excess of magnesium in the precipitating liquor may for instance amount to -75%. In many cases however an excess of 10% will already suilice.
• the excess may be the less, the higher the precipitating temperature, the longer the time of precipitation and the higher the alkalinity of the precipitating liquor.
• Example 1 A solution containing 24.91 grams Co in the form of the nitrate and 3.97 grams MgO likewise in the form of the nitrate, i. e. 16 parts MgO per precipitation. The necessary quantity of carrier material is then added-and the whole of the precipitate flltered oil. A precipitate is obtained which in addition to the total quantity of Co .contains 2.42grams MgO, i. e. 9.75 parts MgO per 100 parts Co.
• Example 2 2 liters of a magnesium nitrate solution, which contains 150 grams MgO, are entered in 30 liters of a boiling ten per cent solution of sodium car-* bonate in the course of about 1-2 minutes, during,
